摘要: 为寻找较好的播种覆盖物,提高播种出苗率和育苗灌溉节水,在吉林东部对长白落叶松种子大田育苗进行不同的播种覆盖物试验,分析不同播种覆盖物对播种出苗率和苗床土壤蒸发量的影响。结果表明:不同覆盖物处理下长白落叶松种子出苗率差异显著,影响出苗率大小的覆盖物依次是锯末、草炭土、豆秸、煤渣灰、河沙;不同覆盖物下土壤蒸发量差异显著,白天影响蒸发量大小的覆盖物依次是草炭土、煤渣灰、裸地、对照、河沙、锯末、豆秸。不同播种覆盖物对土壤表层温度变化影响也不同。

Abstract: A field experiment was conducted to explore better coverage in seedling emergence of Larix olgensis in the Jilin province, five kinds of coverage method were designed in field experiment. Results showed that there were significant different in L.olgensis seedling emergence and soil evaporation in different kinds of coverage, the seedling emergence rate varied from the highest to the lowest was sawdust, turf soil, smash of straw, coal cinder and sand successively. The soil evaporation from the highest to the least was turf soil, coal cinder, CK, sand, sawdust and smash of straw successively. The temperature of soil surface is influenced significantly by different coverage.
